http://www.lady-beetles.com/ Since the early 1990's, lady bugs (Asian Ladybeetles) have become a major pest in thousands of American homes. Our domestic lady bugs are well known for being beneficial beetles that readily feed on aphids, a major pest of gardens and ornamental plants. Needing a biological, natural alternative to pesticides, the Asian lady beetle was imported to feed on aphid pests. The problem with the imported beetles: they do not die off in the winter! Instead, these opportunistic beetles enter our homes seeking shelter and a place to over-winter.
For many years we were all told to simply capture and release all unwanted indoor lady bugs. It has now gotten to the point where this is no longer feasible. When thousands of these pests invade your home, capture and release can be quite a joke. Large populations of lady bugs can also pose the same health hazards to asthmatics as do infestations of German cockroaches.
A few weeks ago we were having the same issue with them but its getting too cold now to see them much.
